I have problem with my laptop (Toshiba Satellite S70-B), I bought 2 years ago and it was working fine until 3 days ago were my Radeon R9 M265X disappeared completely while downloading a game in steam over the night before the problem happened.

I can’t see it in the Device Manager, the only thing is under Display Adapters is Intel HD Graphics 4600:

So basically, I did everything I could find in the internet and still there is only Intel HD 4600 under Display Adapters, I am not sure if the AMD is dead, but I think if it's dead at least I will find some notification on the Device Manager to tell that there is something wrong with the device.

If there is anything I didn't clear it about the problem please ask me to do so.

I didn't solve the problem, the GPU disappear completely like I never had one. Most likely it is dead, at least this my case. I recommend to try what I mentioned above (Things I tried) before jumping to the same conclusion. Basically those all the suggestions to fix the same problem gathered from the Internet.Hope you already solve the problem.Shak

Btw, are you a gamer by any chance? because I remember that the night before the problem, I played Rainbow Six Siege for 6 hours on 10fps and then I woke up to find the GPU dead. Did you encounter the same situation ?

My case i was playing Fortnite suddenly one day i've notice the graphics was very low and when i go to the device manager the main graphic card amd just gone...

All options that i have tried sometimes the card was being detected but not for long, won' t stabilize ...sometimes when the network card shuts down the graphic card shows up from nothing...now lately won't show up not matter what...seems doesn't never exist.

I see, I had so many problems with my laptop as well. tbh I just gave up trying to fix the GPU problem, and I am gaming on the integrated GPU (Intel)Last week my laptop was so slow ( Disk usage always 100%) even after I did a fresh Windows install, so I had to shut down the hard drive, and use Windows to go on external. so far is running like new one. but still no dedicated GPU (AMD).
